Host Bus Interface. The physical bus connecting the LAN9311/LAN9311i to
the host. Also referred to as the Host Bus.
Host Bus Interface Controller. The hardware module that interfaces
theLAN9311/LAN9311i to the HBI.
External system (Includes processor, application software, etc.)
Internet Group Management Protocol
Refers to data input to the LAN9311/LAN9311i from the host
This type of status bit is set whenever the condition that it represents is
asserted. The bit remains set until the condition is no longer true, and the
status bit is cleared by writing a zero.
